Investigation of the Dispersed-Phase Distribution of Organochlorine Pesticides, Polychlorinated Biphenyls and Polycyclic Aromatic Hydrocarbons in Natural Water Systems
The article analyzes the patterns of the dispersed-phase distribution of organic ecotoxicants, namely organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs), in natural water systems. The relationship between the dispersed-phase distribution of individual OCPs, PCBs, and PAHs and the logarithm of the octanol-water partition coefficient log Ko/w (hydrophobicity coefficient) was established. It was shown that the water-soluble part of individual organic ecotoxicants decreases with an increase in their hydrophobicity coefficient.
